We've developed a new app called PixCompare that can help clean up the camera roll on the iPhone/iPad. It's based on something we've been working on the Mac for almost 20 years. The app is free to download and use. There is only a one-time in-app purchase of $0.99 to activate the delete function. PixCompare tries to identify groups of identical or similar pictures. You can then select the ones you no longer need and batch delete all of them. The app finds duplicates based on color, contrast, location, and date/time. This could come in handy, now that many users return from their vacation with full camera rolls!
